Perform multiple requests with configurable concurrency strategy

Executes a list of HTTP requests either sequentially or in parallel. Automatically chooses sequential processing when concurrent_requests = 1 or when there's only one request.

Usage

perform_requests_with_strategy(
  requests,
  concurrent_requests = 1,
  progress = TRUE
)

Arguments

requests

List of httr2_request objects to perform

concurrent_requests

Integer specifying maximum number of simultaneous requests (default: 1)

progress

Logical indicating whether to show progress bar (default: TRUE)

Value

List of httr2_response objects (check status with resp_status()) or error objects for network failures

Details

Returns responses in the order that requests were sent. Since requests use req_error(is_error = ~ FALSE), HTTP error responses (status >= 400) are returned as httr2_response objects rather than being thrown as errors. Callers should check response status with httr2::resp_status() or use httr2::resps_successes() / httr2::resps_failures() to categorise responses.

Examples

if (FALSE) { # \dontrun{
  # Sequential processing
  responses <- perform_requests_with_strategy(
    requests = my_requests,
    concurrent_requests = 1
  )

  # Parallel processing with 5 concurrent requests
  responses <- perform_requests_with_strategy(
    requests = my_requests,
    concurrent_requests = 5,
    progress = TRUE
  )
} # }
